Uncle Mikes Pro PAK Horizontal Shoulder Holster SZ 15

The Uncle Mike's Pro PAK Horizontal Shoulder Holster Size 15 is a concealed carry shoulder rig built for shooters who need comfortable, all-day carry without the bulk. This ambidextrous holster works equally well for right- or left-hand draw, making it a versatile choice for field use, undercover carry, or anyone who prefers shoulder carry over belt options. The horizontal orientation keeps the gun tucked tight against your ribs under a jacket or shirt, minimizing printing while staying accessible when you need it.

What sets the Pro PAK series apart is the thoughtful engineering behind the basics. The holster body uses a thin laminate construction paired with closed-cell foam padding—waterproof, lightweight, and designed to keep your gun secure while protecting its finish. Inside, smooth nylon lining makes for clean draws and smooth reholstering, even in demanding conditions. The shoulder harness itself is stripped down: simple hook-and-loop adjustments let you dial in fit in seconds, with laminated yokes that won't slip or dig in. The soft inner lining grips your clothing without shifting, while the smooth outer surface slides cleanly against jackets without snagging.

Retention is handled by molded thumb and finger breaks adjusted via hook-and-loop, letting you customize draw resistance to your preference. Uncle Mike's wrapped the adjustment straps in Strap Traps—their patented design prevents straps from unraveling and eliminates chafing from repeated draw cycles. An adjustment tool is included to help you dial everything in. Black finish, ambidextrous design, and genuinely lightweight construction make this a practical choice for hunters, tactical shooters, and anyone carrying for extended periods under gear.

Frequently Asked Questions

What size gun does the Pro PAK Size 15 fit?

Uncle Mike's uses a size numbering system for their holsters. Size 15 is their designation for this model, but we recommend confirming compatibility with your specific firearm before purchase. Contact us or Uncle Mike's directly if you're unsure whether your gun fits this size.

Is this holster truly ambidextrous?

Yes. The Pro PAK Size 15 is designed for both right- and left-hand carry without any modification, making it ideal if you shoot from either shoulder or want flexibility in your carry method.

Can I adjust the fit and retention?

Yes. The shoulder harness uses simple hook-and-loop fasteners for quick adjustments, and the molded thumb and finger breaks are also adjustable via hook-and-loop. An adjustment tool is included to help you dial in both harness fit and retention to your preference.

Is this holster waterproof?

The closed-cell foam padding is waterproof and acts as a moisture barrier to protect your gun and the holster itself. While designed to shed water, it's not a fully sealed system—treat it as water-resistant rather than fully submersion-proof.
